Description

The invention relates to radio engineering and can be used in the design and manufacture of aerological radiosondes (ARZ).

A well-known design of the ARZ, see A.A. Efimov, "The principle of operation of the aerological NVK AVK-1," M., Gidrometeoizdat, 1989, pp. 92-94, made of radiolucent material, such as polystyrene, and having the shape of a volumetric rectangle with a halyard for attaching to a pilot balloon, ARZ radio elements and a battery are located inside the structure, and humidity and temperature sensors are carried out. A photo of the indicated construct is attached. The disadvantage of this ARZ is poor wind resistance, i.e. ARZ is subject to a strong “chatter”, which entails mechanical stresses on the structure and fastening halyard, also changes the spatial position, as a result of which the polarization vector of the antenna relative to the polarization of the weather radar antenna can change, which can lead to temporary loss of tracking.

ARZ is known, see the GDR patent No. 228912 A1, the construct of which is made in the form of a ball, humidity and temperature sensors are brought out, electro-radio cells and a battery are placed inside.

Disadvantages:

- the shape of the ball, as is known from mathematics, has a lower volume utilization coefficient compared to a cubic or rectangular one, which entails an increase in size;

- assembly, adjustment, i.e. maintenance, which immediately affects the cost of ARZ.

Known designs of the ARZ company VAISALA, which are a construct of a rectangular shape with dimensions (200 × 150 × 100) mm, and the large size is height and in the working position (flight) is located vertically. The sensors are located in the upper part of the structure, the battery compartment in the middle, and the antenna compartment in the lower part. Access to these parts is via a removable side panel. The case itself is made of polystyrene, see g. VAISALA News, No. 136, 1995, pp. 9-12, Helsinki, Finland - PROTOTYPE.

Its disadvantages are:

- an unsuccessful choice of the shape of the case, which, with strong gusts of wind, causes the ARZ to “lie down” for some time, which leads to a change in the position of the antenna in the plane of polarization, as a result of the tracking weather radar, it loses the target, and with it the necessary weather information;

- the presence of a removable panel complicates the design and does not provide convenient access to all parts of the ARZ.

In general, you can notice that the choice of a construct (an external form, and therefore an internal structure) is not such a simple task, because The construct must satisfy the following conditions:

- ease of assembly;

- convenience when setting up and searching.

An object of the invention is to improve performance due to:

- selection of the shape of the case;

- convenient access to all internal parts of the ARZ to ensure settings and troubleshooting;

- minimum dimensions and weight;

- maximum resistance to wind gusts;

- minimum cost, because the number of ARZs launched into the atmosphere is approaching one million all over the world - therefore, there is fierce competition between ARZ manufacturers, so Finland is aggressively making its way to the Russian market, lowering the price of its ARZs. Therefore, the patent protection of the ARZ is also an urgent task, at least in our country.

The global average price of one ARZ (without a pilot ball) is in the range of $ 40-50. Reducing prices by at least one dollar, multiplied by 100,000-200,000 ARZs produced in Russia, gives tangible benefits.

This goal is achieved by the fact that the proposed design of the aerological radiosonde, comprising a housing, meteorological sensors, a radio telemetry unit with an antenna system and a power source, characterized in that the radiosonde housing has a circular shape in plan, beveled in the upper part to the top, and in the middle and lower parts - to the bottom, to the flat cover of the radiosonde, horizontally attached to it is a temperature sensor on the remote boom, and on the base of the cover is attached a humidity sensor with a protective peak above it; that the humidity sensor is mounted on the cover of the radiosonde with a protective visor above it in the form of an overturned saucer, on the sides of the humidity sensor along the perimeter of the cover there is a beveled circular windshield; the casing is made of radio-transparent material with a halyard for attaching the pilot ball, the transceiver, the radio telemetry unit, the power supply and the antenna system are placed inside the casing, all electrical connections are made by wires directly or through the connectors, the antenna system is placed inside the radio-transparent casing to avoid mechanical damage, the dimensions of the casing are selected as minimum and are determined by the dimensions of the electro-radio elements located in it.

In FIG. Figures 1-4 show the design of the radiosonde, which shows: 1 - housing, 2 - telemetry compartment, 3 - cover, 4 - remote boom with a temperature sensor at the very end, 5 and 6 - voids, 7 - battery compartment, 8 - sensor humidity with a converter, 9 - wires from the temperature sensor (Fig. 2) and from humidity sensors, 10 - a cover over the humidity sensor 8, 11 - a circular windproof screen.

ARZ building 1 has a circular shape in plan (top view in sections), beveled in the upper part to the top, and in the middle and lower to the bottom, the bottom and top cover are flat. The diameter of the ARZ in the maximum part lies within 151 ± 10 mm, the height in the range of 161-190 mm. A cord (halyard) is attached along the side surface of the ARZ to fasten it to the pilot balloon (not shown conditionally). A temperature sensor is fixed to the upper part of the ARZ on the remote boom 4 (at its very tip), the lid 10 is made in the form of an overturned saucer. Inside the ARZ there are a telemetry unit 2, a battery compartment 7 with a cover 3, in the lower part of the ARZ (the most oblique) there is an antenna system containing the antenna itself and the transceiver (PPR), the antenna is an adjustable asymmetric λ / 4 vibrator (the antenna and PPR are conditionally not shown), from the humidity and temperature sensors are wires 9 in the form of twisted pairs. The case of ARZ is made of radiolucent material, for example polystyrene (shown by hatching).

The selected shape of the hull is least affected by wind, as ARZ in the proposed form simply rotates (rotates) around its vertical axis in one direction or another and does not "lie" on its side, in extreme cases, only slightly deviates from the vertical, which ensures its stable tracking of weather radars.
